  1. WELL AGREE WITH THAT BUT IT DOES SEEM DIFFERENT BETWEEN PUMPS AND HAVENT BEEN GIVEN ENOUGH INFO OR REASONING TO LET IT GO WITHOUT ANY INVESTIGATION. WE FILLED OUR 107 FOR LOCKHEED (ONLY GOD KNOWS WHEN THEYLL GET BACK TO US), BUT FIGURED MAYBE SOMEONE HERE HAS SEEN THIS BEFORE AND DID BETTER RESEARCH. AND I HAVE TALKED TO PLENTY OF PILOTS AND FE'S THAT SAY THEY SEE A DRASTIC DROP WITH ONE ENGINE NO LIGHT AND ONLY ONE FE HAS SAID THEY HAVE SEEN THE LIGHT WITH ONE ENGINE. (UNLESS THERE WAS AN ISSUE).
  2. is that a newer thing, work on 66's and havent seen or heard of a button to activate the diverter panel or valve. seems kinda weird cause u would need two guys in the cargo door for utility and booster. and during troubleshooting couldnt u just put ur hand on the valve and feel for it opening and closing
  3. well the thing we were wondering was the gap in pressures. and the only thing we could find was under the -1 and it says to expect a drop in pressure but doesnt reference a light coming on. and the dash one says if the light illuminates to shut the pump off, which on approach with one left engine and if the light came on the other left engine that would leave u with no gear.
  4. also swapped the parker out again thinking bad pump from supply, but same numbers.
  5. we had a bad abex pump on #1 eng. swapped out with parker and ran engines. all ops cks were good. original write up was landing gear down and pump light came on. so we recreated it and nothing. we ended doing it again with #2 pump off and went flaps down and while moving flight controls (not what i was supposed to do but new to hydraulics and did it thinking everything would ck good) and pressure dropped to 700 and the pump light came on. switched #1 off and put #2 on (parker pump) and the pressure dropped to 2000 with no light. switched pumps from #1 to #2 and #2 to #1, issue followed pump. been told this is normal but just doesnt make much sense to me, because of the issue of losing the engine with abex on it. scenarios: one engine flaps and flight controls moving parker 700 psi abex 2000 psi one engine just flaps parker 1200 psi abex 2500 psi one engine just flight controls parker 3000 psi +/- 200 psi abex 3000 psi +/- 200 psi both engines all tests 3000 psi
